Dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) spectroscopy is a popular and growing application for high-frequency, continuous wave (cw) gyrotrons that produce powers in the range of tens to hundreds of watts at millimeter-wave and terahertz frequencies. As an original equipment manufacturer of gyrotrons for Bruker Biospin DNP systems, CPI has developed a series of high-frequency gyrotrons, the most recent of which is a 50 W, 593 GHz device for a 900 MHz NMR spectrometer. Design and performance details for the 593 GHz gyrotron will be discussed.
